AACCI Method 32-10.01
Crude Fiber in Flours, Feeds, and Feedstuffs

VIEW METHOD

Objective
To determine crude fiber in flours, feeds, and feedstuffs. Crude fiber is the loss on ignition of the dried residue remaining after digestion of the sample with 1.25% H2SO4 and 1.25% NaOH solutions under specific conditions. This method utilizes the Oklahoma State filter screen or the Modified California State Buchner funnel for filtration and uses prepared ceramic fiber as a filtration aid instead of asbestos. This method is applicable to grains, meals, flours, feeds, and fiber-bearing material from which fat can be extracted to leave workable residue.
